Cons
Con Extremely buggy
Around mid-2015 Downcast implemented some code that started to leave infinite loop processes that have the potential to cause the phone to heat up, lag, crash Downcast, or crash other apps. The bugs have only continued to get worse. Go with Overcast or Pocket Casts, or even Podcatcher for the Downcast feel.
Con Doesn't sync with iTunes
Con The ability to discover new or relevant podcasts ("Recommended for you") is practically useless
Similarly, the search feature seems to only look for podcast hosts or podcast names. You can't find all podcasts that has a specific guest.
Con Very barebones webapp
Con Unplayed episodes
Does not have the ability to show unplayed episodes for individual podcasts.
Con Adds a subscription even after listening a single episode
It is not possible to pick a single Podcast Episode to download without having to subscribe to yet another Podcast feed (that shows up in your Subscriptions List).
Con Can't set a subscription to NOT download any episodes
By subscribing to a podcast you have to set it to download at least one (most recent) episode. There is the setting to set the podcast to stream only, but would prefer to set to zero downloads and choose which episodes to download individually.
Con Unable to sort by playtime
It would be nice to have the ability to sort tracks like podcasts from the shortest to the longest.
Con No paged RSS feeds
this Podcatcher does not support reading longer RSS Feeds that are split into several pages (for faster access).
